Carton for radio tubes



March 28, 1939. c. M. KNAUR CARTON FQR RADIO TUBES Filed Dec. 15, 1937Patented Mar. 28, 1939 UNITED STATES PATENT OFFICE Claims.

This invention relates to certain new and useful improvements in cartonsfor radio tubes and the like, the object being to provide a cartonformed of two members, one telescoped within 5 the other in order toallow the inner member to move in respect to the outer member so thatthe tube carried thereby can be extended to permit the tube to beexamined and tested and yet prevent it from being removed so as toprevent the bootlegging of an inferior product.

Another object of my invention is to provide a carton which isexceedingly simple and cheap in construction, each member being formedof a single piece of material bent into its proper l5 shape and securedtogether in such a manner that one is free to move in respect to theother and yet is prevented from being extended to such an extent thatthe tube carried thereby can be removed.

Another and further object of the invention is to provide a cartonhaving three supporting means for the tube, whereby the tube is heldfirmly so as to prevent the same from being injured in shipping.

Other and further objects and advantages of the invention will behereinafter set forth and the novel features thereof defined by theappended claims.

Figure 5 is a detail perspective view of a portion of the inner membershowing the yieldable tongue. A

My improved construction of carton is formed of an outer tubular memberA and an inner tube supporting member B, each formed of'a single pieceof material, the inner member being telescoped within the other member.

The outer member is formed of a rectangular piece of material, such ascardboard or the like bent into tubular form having its ends overlappedand glued together. The tube thus formed is substantially rectangular incross sec- 55 tion and it is, of course, understood that it can beformed of any shape desired without departing from the spirit of myinvention.

The inner member B is formed of a strip of material, such as cardboardor the like, scored transversely on lines I, 2, 3, 4, 5 and 6 and bent 5into an oblong shaped body having opposing walls 1 and 8, end members 9and I0 and a partition H. The wall I is provided with a slit It toreceive a locking tongue I3 formed on the end of the strip for lockingsaid body in its bent shape. The wall 8 is provided with side flaps l4and i5 bent inwardly as shown on scored lines to form opposing side wallportions and the end members 9 and 10 are provided with flaps l6, l1, l3and I 9 bent outwardly on scored lines as shown 15 in Figure 4 toposition and hold the body within the outer member A. The partition llisprovided with a flap 20 bent at right angles thereto on scored linesand adapted to engage the end member ID for positioning the partitionwithin the body.

The end members 9 and. I0 and the partition H are apertured to receiveand support a radio tube C to prevent it from being injured in shippingas it will be noted that the partition surrounds the tube intermediateits ends to hold the tube properly centered within the carton and thatthe side walls and the side flaps form walls for protecting the tube.

The wall 8 is cut to form a substantially T- shaped tongue 2|, the stemof the tongue being scored transversely as shown at 22 in Figure l andbent back upon itself as shown in Figure 4 and the head of the tongue isconnected to the outer member A by a rivet or the like 23 as shown inFigures 2 and 3. The yielding portion 22 is formed by a plurality ofscores arranged parallel to one another and limits the movement of theinner member within the outer member a predetermined distancesufiiciently to allow the tube carried thereby to be extended fortesting and to be withdrawn to a position so that the ends of the sideflaps of the end leaves will be flush with the ends of the outer memberA, as shown in Figure 2.

By constructing the carton of two members, one telescoped within theother and each member being formed of a single piece of material,

I am able to manufacture a carton very cheaply which has all of theadvantages of cartons now in use to prevent the bootlegging of aninferior product and yet can be manufactured much cheaper and has manyadvantages over the other constructions in view of the fact that itsupports the radio tube more firmly to prevent the same from vibratingin shipping or being displaced from the end members.

Assuming that a radio tube is: in position within the carton as shown inFigure 2, when it is desired to test or examine the tube, by exertingpressure on the end member of the tube, the inner member will slidewithin the outer member .so as to expose the tube as the yieldingportion 22 of the tongue allows the inner tube to move within the outertube a predetermined distance which is suflicient to examine the tubeand yet prevent the tube from being removed.

What I claim is:

1. A carton for radio tubes and the like consisting of two members, onemember telescoped within the other, each member being formed of a singlepiece of material, the inner member having a tongue out out of one wallthereof and bent back upon itself and permanently connected to the outermember to allow said inner member to move a predetermined distancewithin the outer member.

2. A carton for radio tubes and the like consisting of two members, onemember telescoped within the other, each member being formed of a singlepiece of material, the inner member having a tongue out out of one wallthereof and bent back upon itself and permanently connected to the outermember, a portion of said tongue being yieldable to allow said innermember to move a predetermined distance within the outer member.

3. A carton for radio tubes and the like comprising an outer tubularmember, an inner tube supporting member movably mounted therein formedof a single strip of material bent into oblong shape having aperturedends and an apertured partition to receive and support a tube and atongue cut out of one wall of said inner member having a permanentconnection with the outer member for limiting the moment of the innermember within the outer member.

4. A carton for radio tubes and the like comprising an outer tubularmember and an inner tube supporting member movably mounted therein, theinner member being formed of a single strip of material foldedtransversely into oblong shape to form ends and a transverse partition,the ends and partition being apertured to receive and support a radiotube, a tongue out out of one wall of the inner member and bent backupon itself adjacent its connection with said wall and extendingoutwardly beyond the adjacent end and connected to the outer member toform a yieldable connection between said members to limit the movementof the inner member within the outer member.

5. A carton for radio tubes and the like comprising two members, onetelescoped within the other, the inner member having a tongue out out ofone Wall thereof and permanently connected to the outer member forlimiting the movement of the inner member within the outer member.
